Please explain why i am getting the following question wrong.

This is the question and its a $2$ parter. Assume the FORM sets method $=$'GET' and the following input tag: I have to assing the value from the field shown in the input tag to the variable $stroe$\_$IDvalue.

This was my answer and it was wrong: $<$$store$\_$vcalue$>=$$$\_$GET$[\text{'}$store$\_$ID$\text{'}]$;

second portion same directions but to the following inpurt tag assinging the value from the field shown to variable $part$\_$numbervalue

this was my answer and I was wrong $part$\_$numbervalue$=$$$\_$GET$[\text{'}$part number'$]$;
